4. The way in which a number of computers are connected
together in a network is called topology. It is the physical layout
or arrangement of computers in a network.
There are five basic topologies for connecting computers
in a network.
These are:
1. Bus topology 2.Star topology
3. Ring topology 4. Tree topology
5. Mesh topology
5. 1. Node are connected to a backbone.
2. A special wire called the bus connects node to
backbone.
3. The ends of the bus are closed with
terminators.
4. Bus topology is commonly used for small and
simple networks.
6. The sending computers attaches the address.
Then data sent to the bus.
only that computer accepts the data whose address
matches.
Only one computer can send data at a time.
7.
8. 1. It is simple and reliable for very small
networks.
2. It is easy to install.
3. It requires minimum length of
communication cable.
4. Time and cost effective.
9. 1. Supports only a small number of
computers.
2. If any fault occurs in the entire network
whole network will be shutdown.
3. Troubleshooting is to difficult to resolve.
10. • In star topology, all computers or nodes are directly connected
to a central device. The central device that connects the nodes
is called hub.
11. • Each computer on a star network communicates with the
central hub. The hub then sends data to the destination
computer or computer.
12. 1. It is easy to maintain and modify
network.
2. Adding or removing computers can be
done without disturbing the network.
3. Less cable length is required.
13. 1. Finding of fault is difficult.
2. It is more expensive.
3. If the central hub fails, the whole
network breaks down.
14. In ring topology, each computer or node is
connected to the next computer and the
last computer is connected to the first.
Thus, a ring of computers is formed.
15. Every computer receives message from
the previous computer and transmits it
to the next computer till the
destination computer receives the
message.
16.
17. 1.It is less expensive then Star
Topology.
2.Every computer has equal
access to the network.
3.Additional node is easy to add.
18. 1.Failure of one computer can
affect the whole network.
2.It is difficult to troubleshoot.
3.Adding or removing a computer
affects the whole network.
19. A tree topology combines the
characteristics of bus and star topologies. It
consists of different groups of computers
attached in star topology. The groups are
then connected to a bus backbone cable.
Tree topology is used for the expansion of
an existing network.
20.
21. 1. Point-to-point wiring for individual
segments.
2. Supported by several hardware and
software manufactures.
22. 1. Overall length of each segment is
limited by the type of cabling used.
2. If the backbone breaks down, the
entire network goes down.
3. It is more difficult to configure and
wire than other topologies.
23. In a mesh network topology, each of the network node,
computer and other devices, are interconnected with one
another. Every node not only sends its own signals but also
relays data from other nodes. In fact a true mesh topology
is the one where every node is connected to every other
node in the network. This type of topology is very
expensive as there are many redundant connections, thus
it is not mostly used in computer networks. It is commonly
used in wireless networks. Flooding or routing technique is
used in mesh topology.
24.
25. 1. The use of dedicated link guarantees
that each connection can carry its
own data load. It eliminates the
traffic problem.
2. If one link becomes unusable, it does
not harm the entire system.
3. It is easy to troubleshoot.
26. 1. A full mesh network can be very
expensive.
2. It is difficult to install and
reconfigure.
3. There are high chances of
redundancy in many of the network
connections.
